EP-4703580-A3 - DEVICE, ENERGY CONVERSION SYSTEM AND FLUID-OPERATED WAVE UTILIZATION SYSTEM

Abstract

The invention relates to a device for converting kinetic energy, in particular wave energy of a fluid, into electrical energy, an energy conversion system and a fluid-flowing wave utilization system. The device comprises a hollow body and a base body, which is supported from an inner wall of the hollow body by means of at least a first spring and a first energy dissipation device of variable length arranged at a distance from the first spring, and has at a first end a sleeve with a coil arranged along the longitudinal extent of the sleeve and at a second end a permanent magnet inserted into and movable within the sleeve, wherein an electrical energy is generated when the permanent magnet moves along the longitudinal extent of the sleeve, such that a first kinetic energy acting on the hollow body at a first time accelerates the device in a first direction, whereby the base body is deflected in a second direction oriented opposite to the first direction, thereby initiating a movement of the permanent magnet relative to the sleeve and thus converting the first kinetic energy at least partially into electrical energy, wherein the first spring is arranged with a first end on the base body and with a second end on the inner wall of the hollow body. The invention relates to a wave energy generation system for producing electrical energy from the kinetic wave energy of a fluid, comprising a frame through which the fluid flows, with a wave inlet and a wave outlet, and at least a first energy absorption device and a second energy absorption device, which are arranged in a region between the wave inlet and the wave outlet and generate electrical energy when accelerated, wherein the first energy absorption device is connected to the second energy absorption device by means of a first connecting element and/or the first energy absorption device is connected to the frame of the wave energy generation system by means of a second connecting element and/or the second energy absorption device is connected to the frame of the wave energy generation system by means of a third connecting element, such that a predefined range of motion of the second energy absorption device relative to the first energy absorption device and/or the second energy absorption device and/or the first energy absorption device relative to the frame is realized by means of the first connecting element, the second connecting element and/or the third connecting element.
